Optimarin AS, based in Stavanger, produces a solution for treatment of ballast water according to IMO's 'Ballast Water Convention'. Klaveness Marine owns approx 40 %.
The Type Approved Optimarin Ballast System (OBS), is based on solid separation (filter) as pre-treatment and high doses of UV irradiation for inactivation of marine organisms, viruses and bacteria, without affecting the normal operation of the ship. Ballast water is UV treated both during ballasting and de-ballasting to ensure the dual UV effect. Ballast water is only filtered during ballasting.
